想用中断的方式来进行串口发送，更改HAL_DMA=FALSE,编译之后为什么有好多错误？

可以在 hal_board_cfg.h 里面选择:


* @fn HalUARTOpen
*
* @brief Open a port according tp the configuration specified by parameter.
*
* @param port - UART port
* config - contains configuration information
*
* @return Status of the function call
*****************************************************************************/
uint8 HalUARTOpen(uint8 port, halUARTCfg_t *config)
{
(void)port;
(void)config;

#if (HAL_UART_DMA == 1)
if (port == HAL_UART_PORT_0) HalUARTOpenDMA(config);
#endif
#if (HAL_UART_DMA == 2)
if (port == HAL_UART_PORT_1) HalUARTOpenDMA(config);
#endif
#if (HAL_UART_ISR == 1)
if (port == HAL_UART_PORT_0) HalUARTOpenISR(config);
#endif
#if (HAL_UART_ISR == 2)
if (port == HAL_UART_PORT_1) HalUARTOpenISR(config);
#endif
#if (HAL_UART_USB)
HalUARTOpenUSB(config);
#endif

return HAL_UART_SUCCESS;
}
